CLEANING AND la'kINT-REMOVING APPARATUS.

Application filed July 25, 1921.

T 0 all whom it may concern Be it known that 1, DAVID P. CLEVELAND, a citizen of the United States, residing at Dallas, in the county of Dallas and State iii of Texas, have invented certain new and useful Improvements in Cleaning and Paint- Removing Apparatus, of which the following is a specification.

This invention relates to new and useful improvements in cleaning and paint remov- 'ing apparatuses;

v The purpose of the invention is to provide an apparatus in which two functions may be combined. First, to provide an apparatus whereby an equalized air pressure may be employed within a receptacle for discharging therefrom a suitable cleaning fluid for the purpose of removing dirt, grease and the like from various articles. The second function is to utilize the same receptacle for the heating of a chemical so- I 0 lution, whereby the gaseous pressure in the receptacle will discharge the chemical therefrom, which may be combined with the equalized air pressure for spraying on a painted surface for the purpose of removing the paint from said surface.

In carrying out the invention I provide a tank within which is supported an air drum of less diameter. A. compressed air conductor leads into the drum and a discharge pipe leads from the drum. A by pass connection is established between the compressed air conductor and the tank so that compressed air may be delivered into the tank as well as into the drum. Means is provided for heating thetank and a fluid conductor leads from the tank so that the chemicals or cleaning fluid may be conveyed from said tank. Means for filling the tank together with a pressure gauge and a safety valve are also included.

' fication and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

portions being broken away to illustrate interior constructions, and

' Fig. 2 is a transverse sectional. view on the line 2-2 of Fig. 1.

In the drawings the numeral designates an elongated metal tank preferably of a cylindrical shape and suitably constructed and lined to resist chemical action from acids and the like. The tank may be mounted upon supports 11, at each end or in any suitable way and may either be stationary or portable. At one end of the tank a glass liquid gauge 12, is provided for indicating the level of the fluid within the tank. At the center of its bottom the tank has a sump 13, from which a discharge pipe 14. extends. A cut-off valve 15 is included in the pipe 14:.

I dispose concentrically within the tank a cylindrical drum 16 preferably considerably less in diameter and also less in length than the tank. This. drum is held in position by brackets 17 or other suitable means. An air supply pipe 18 leads thru the tank to the drum. A by-pass pipe 19 including a cutoff valve 20 extends from the pipe 18 to the tank 10. A cut-off valve 21 is located in the pipe 18 between the tank and the point at which the by-pass pipe is connectech so that by closing the valve 21 air cannot pass into the drum 16. A controlling valve 22 is included in the pipe 18 in advance of the connection with the pipe 19, so that the supply of air may be cut oif from both the tank and the drum. The pipe 18 is connected with a suitable air compressor or other source for supplying compressed air which is not shown. An air discharge pipe 23 leads from the drum thru the tank and iueludes exteriorly of the tank a cut oil valve 24.

A filling pipe 25 isv connected in the top of the tank 10 and is surmounted by a cross connection 26. An angular pipe 27 leads from one side of the cross connection and supports a pressure gauge 28, while a similar pipe 29 leads from the other side of the connection and supports a safety pressure valve 80, which may be of any suitable construction and is well known in the art. A feed valve 81 is mounted on top of the connection 26 and supports a filling hopper The valve 81 is closed when the apparatus into the drum, a by-pass pipe leading from the air supply pipe to the tank and including a cut-off valve, cut-ofi' valves mounted in the air supply pipe on each side of the 5 point of connection with the by-pass pipe, an air discharge pipe leading from the drum thru the tank and including a cutoff valve, burners for heating the tank 10- catcd under the same, a safety pressure valve connected with the tank, and a pressure 39 gauge connected With the tank.

In testimony whereof I aifix my signature.

DAVID P. CLEVELAND.
